CVE-2013-2224

Status Candidate

Overview

A certain Red Hat patch for the Linux kernel 2.6.32 on Red Hat Enterprise Linux (RHEL) 6 allows local users to cause a denial of service (invalid free operation and system crash) or possibly gain privileges via a sendmsg system call with the IP_RETOPTS option, as demonstrated by hemlock.c. NOTE: this vulnerability exists because of an incorrect fix for CVE-2012-3552.

Red Hat Security Advisory 2013-1450-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that the fix for CVE-2012-3552 released via RHSA-2012:1540 introduced an invalid free flaw in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to corrupt kernel memory via crafted sendmsg() calls, allowing them to cause a denial of service or, potentially, escalate their privileges on the system. An information leak flaw was found in the way Linux kernel's device mapper subsystem, under certain conditions, interpreted data written to snapshot block devices. An attacker could use this flaw to read data from disk blocks in free space, which are normally inaccessible.

Red Hat Security Advisory 2013-1195-01 - Red Hat OpenStack 3.0 includes a custom Red Hat Enterprise Linux 6.4 kernel. These custom kernel packages include support for network namespaces, this support is required to facilitate advanced OpenStack Networking deployments. A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol implementation handled duplicate cookies. If a local user queried SCTP connection information at the same time a remote attacker has initialized a crafted SCTP connection to the system, it could trigger a NULL pointer dereference, causing the system to crash.
